Josef, I've added you to CC because this package is a prerequisite for the next GIMP stable release 2.10 (whenever that one is ready ;) and of course the unstable releases up to that -- I'm currently working on getting 2.9.4 built for the gimp-unstable COPR.

will review very soon.

That's interesting... Can you check if it's correct locale name "ar_AR" and if it is, please open bug against package "filesystem" which doesn't know anything about that lang.

libmypaint explicitly requires sphinx-build-2, su change to python2-sphinx.

* Missing BR: gcc

Thanks for taking the review!

The pkgconfig package contains the %{_libdir}/pkgconfig directory and is normally used for building with the library.

Why? Listing the directory and the files separately, or just the directory recursively doesn't make a difference in the result.

Because git-tagged tarballs don't include all files contained in a make-dist tarball, and we're ultimately targeting official releases.

I'm pretty sure it isn't a correct locale name, I've submitted a fix/pull request to rename the file:

Fedora 23 doesn't know about python2-sphinx, I've fixed that for Fedora 24 and later.

There is automatic requirement for pkgconfig in RPM.

It depends. For example, if they will add Gio-99.typelib into girepository you will not notice by using '*'.

I tried to install this on F24 and noticed that there are file conflicts with mypaint-1.1.0

I think this package needs 
Conflicts: mypaint < 1.3.0

ping?

Oh, hello 2017! ;)

Sorry for the long wait.

Actually, rpm-build requires pkgconfig but we can't rely on that to be available -- people might want to build software against libmypaint without packaging it.

Understood, I've added each file in these directories explicitly.
